POLYGRAPH EXAMINATION OF THE SUSPECT AND ITS “EVIDENTIARY” VALUE IN THE CRIMINAL PROCEDURE

Abstract

The polygraph, very often refered to as a lie detector, does not discover directly
the false answers of the tested person, but rather the emotions of fear and anxiety that
usually follow the fake answers.2
In other words, the physiological phenomena that the
instrument measures and that the chart preserves are believed to reveal deception, but
the instrument does not register the deception directly. Rather, it is said to measure
physiological responses that are believed to be stronger during act of deception than at
other times. 3 To be able to understand the meaning of the polygraph testing, and
therefore to assess how reliable it is to determine quilt or innocence, we need to focus
on the issues concerning the idea and the problems behind the polygraph.
